---------------------------------------------------------------
Note: The enum names with OFFSET are meant to reflect these Java 8 names:
* java.time.format.DateTimeFormatter.ISO_OFFSET_DATE
* java.time.format.DateTimeFormatter.ISO_OFFSET_DATE_TIME
* java.time.format.DateTimeFormatter.ISO_OFFSET_TIME
There is no "TIME ZONE" in the names.
For 2.x, we should keep the "8601" in the name for consistency.
For 3.x, we should consider dropping "8101" since Java does not use it. I do
not foresee another ISO spec in this dept. where we would then need to
distinguish between the two.

> Project: Log4j 2

> Hi there!
> There might be a small issue with the Pattern Converters regarding Timezone
> management:
> http://logging.apache.org/log4j/2.x/manual/layouts.html#PatternLayout
> Right now, these patterns:
> * {{"%d\{ISO8601_BASIC\}}}
> * {{%d\{ISO8601_BASIC\}\{UTC\}}}
> Give the same results:
> * {{20160104T204256,048}}
> * {{20160104T204256,048}}
> However, with a deeper look at the ISO-8601 standards, the second one with
> {{"\{UTC\}"}} should properly add the Timezone at the end of the timestamp.
> Reference: https://en.wikipedia.org/wiki/ISO_8601#Times
> {quote}
> *UTC*
> If the time is in UTC, add a Z directly after the time without a space. Z is
> the zone designator for the zero UTC offset. "09:30 UTC" is therefore
> represented as "09:30Z" or "0930Z". "14:45:15 UTC" would be "14:45:15Z" or
> "144515Z".
> UTC time is also known as 'Zulu' time, since 'Zulu' is the NATO phonetic
> alphabet word for 'Z'.
> *Examples*
> <time>Z
> <time>±hh:mm
> <time>±hhmm
> <time>±hh
> {quote}
> As of ISO-8601, the results should be one of the following (configurable?):
> * {{20160104T204256,048Z}}
> * {{20160104T204256,048+00:00}}
> * {{20160104T204256,048+0000}}
> * {{20160104T204256,048+00}}
